thermostat housing

[90VN55]

i have just replaced the thermostat and put it all together and a bit of coolant is squirting out where the theremostat meets the engine. is there an easy way to fix this or do i have to rip it all off again?

p.s. i put a new o ring on aswell

[xcop5l]

that usually means the thermostat isnt seated properly or the gasket hasent seald yes you will have to pull it off again

[90VN55]

so there is a gasket?
the bloke from holden said there is none

[xcop5l]

yeah they have a gasket not an o ring

mines different it has a O-ring

[xcop5l]

thats strange

[90VN55]

mine is a series 1 so the housing is at the back of the engine under the throttle body.
and there is only 1 bolt to hold it on

Unless the V6 is different xcop5l, cause I know the 5.0lt is a gasket........

This is not really related, but I have to do this soon as well and was wondering if you had troubles getting the housing off and If it was corroded at all.
Didnt you just find if it needed a gasket or o-ring when it was taken off?

i found out what the problem was the o-ring was pinched under the housing.

vn6pwr the housing came off relatively easy but in the gregorys manual it says to take the throttle body and inlet manifold adaptor off but u cant take the inlet manifold adaptor until u take the thermostat housing off.

but take the throttle body off and u should be right

Put some rubber grease or vaseline on the 'O' ring before you install the thermostat housing and it will help the 'O' ring slide into the bore easier without catching and allow the 'O' ring to displace to the shape of the bore easier. Neither of those two lubricants should harm anything.

its all good now. i bought a new O-ring and put a bit of soap on it and it slipped on easy

[90VN55]

dont suppose you know how to bleed the air out of the system?

i done mine saturday... those frikkin O rings suck balls..... i oiled it up a bit and fiddled it in.... good idea... maybe........ just leave ur rad cap off and run the engine til she warms up and keep toppin it up bout 20-30 mins

take the return hose thingy off the inlet manifold and then fill up till it comes out that, then put it all back together fill it up again and then run it till its warm and the fan cuts in and out, then check it and make sure its still full, if not fil it up again, thats what we do at work but, might be other ways to do it

what do you mean inlet manifold?

if its the pipe that goes onto the housing then i wish it was that easy

[potshots007]

the little hose that goes fromt the resoviour to the inlet meanifold, must be only like 1/2" hose or something about 30 cm long, take itt off at the inlet side and hold it up a little and then just keep filling the resoviour until there is free flowing water coming out the inlet manifold pipe, just go get the air out of it then put the hose back on, easy as piss, then fill it up and warm it up and recheck it

and turn on the heater.
